Chapter 14: Agricultural Management and Pest Control
Agriculture in action: Why is "shifting agriculture's" negative impact on the environment relatively low? Why would anyone want to use this method?
What are some of the pros and cons of:
Shifting Agriculture?
Alex: Shifting agriculture allows for short term use of nutrient filled soil where small areas of forest are burned down. The benefit of this is that once the area is abandoned, the surrounding forest helps to recolonize the area through succession. This form of agriculture works very well when practiced by small populations, in areas with thin, nutrient-poor soil. However, this method can be destructive if used by larger populations. When used by larger populations, the plots of forest burned are larger and have less time to recover, preventing the forest from reaching full succession. In turn, this damages the soil and changes the nature of the forest.
Labor-Intensive Agriculture?
Mechanized Agriculture?
Click on the link below, watch the video, and respond to the following questions.
This video depicts a rather recent examination of the use of Pesticides, have things changed all that much since the years of Silent Spring's publishing? What problems still need to be adressed?
What are the incentives of using pesticides?
Max: Improved crop/livestock yields, diseases contained geographically, farm and agribusiness revenues, nutrition and health improved, workforce productivity increased, etc.
Do you think pesticides have any place in the world?
Within sustainable agriculture, there are principles concerning the practice of controlling weeds and pests, what are these guidelines?
What are the national organic food growing standards? What incentives are their to being an organic farmer? What are the difficulties?
Describe some of the different techniques for protecting soil and water resources.
There are many different ways to go about integrated pest management, talk a bit about the pros and cons of those listed below.
